Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.


To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • Vermiculite Compressive Strength

    Does anyone know if the hearth four inch vermiculite-cement insulation layer is stable enough to support a six foot brick flue? Vermiculite seems to be too soft and is causing concern. If any of you have or know of any ovens with longer flues, please advise.

    Yes it is stable. My oven has over 7 inches of thermal mass for the floor and dome. So it's almost twice in weight of a standard oven and my vermiculite has not settled at all. You are good to go.

    I though the same thing when I built mine. I made a test piece and was truly surprised how strong it is.

      How about a half ton oven sat on 1" of vermiculite?

        You may need to put some sort of support ring around the outside of the vermcrete to contain and protect the outer edge.

          I built my oven on a 4.5 inch layer of 5:1 vermicrete. As I was mortaring the oven, I used the excess mortar on the outer edges. I finally mixed a big batch and finished covering the ends of the vermicrete layer, worked fine.

            Thanks for the comments. I feel better about the vermicrete supporting the heavier than usual flue.
